"The remains are in a bad state of conservation and do not allow us to do an individual identification of Miguel de Cervantes. But we are sure what the historical sources say is the burial of Miguel de Cervantes and the other people buried with him is what we have found," forensic scientist Almudena Garcia Rubio said, according to the BBC.

Considered the first modern novel, “The Ingenious Gentleman Don Quixote of La Mancha” was published in two parts in 1605 and 1615.

“We are convinced that among these fragments, we have something of Cervantes. However, I can’t say that with absolutely certainty,” lead researcher Francisco Etxeberria said, according to the newspaper.

Cervantes had requested to be buried in the convent, but the location of his tomb was lost during a subsequent construction project.

Nicknamed the “Prince of Letters,” Cervantes is believed to have died at age 68 with only six teeth remaining and injuries sustained in the Battle of Lepanto in 1571 that caused the loss of movement in his left hand, Bloomberg reported.

Mayor Ana Botella said Madrid is considering establishing a memorial site at the convent.

Twitter users commented on the discovery.

This is really cool—Cervantes' tomb has been found: http://t.co/7twzkbDmdQ Don Quixote is such an epic, funny, novel; and 400 years old.
